email: Add support for Dovecot 2.4
Sunil:

- When dovecot package is upgrade from 2.3 to 2.4 during distribution upgrade,
automatically re-run setup.

- Upgrade existing setups to new scheme by re-running setup with incremented app
version.

- Don't query dovecot version during app initialization. Instead overwrite the
DropinConfigs component to query dovecot version during setup and enable
operations.

- Use apt.Cache() to retrieve the installed version of dovecot package. Use
plinth.utils.Version to parse the version and perform a comparison.

- Split even configuration files that have not changed for simplicity.

- Add/update links in Dovecot configuration files.

Tests:

- Install email app on a testing container. Ensure that all files in
/etc/dovecot/conf.d/ are linked properly to 2.4 versions. TLS configuration is
accurate. Use Sogo to test login and sending mails.

  - User with LDAP account and correct password is able to login.

  - User without LDAP account or incorrect password is unable to login.

  - Send mail with Sogo to another account on the server. Notice that mails are
  stored in /var/mail/{user}/mail/ with mail:mail ownership in mbox format.

  - Logging in with email such as user@example.com works. Capital letters are
  allowed.

  - "Archive", "Drafts", "Sent", "Junk", "Trash" folders are automatically
  created and are marked with special flags. Creating additional folders such
  as "Sent Items" also results in them having special flags.

  - Thunderbird is able to connect via SSL with a self-signed certificate
  exception.

  - When an example spam message is sent, it is automatically moved to "Junk"
  folder after getting marked by rspamd.

  - When a message is moved to Junk folder, it is learned as spam by rspamd as
  seen in its admin console.

  - When a message is moved out of Junk folder (to other than "Trash" folder),
  it is learned as not-spam by rspamd as seen in its admin console.

- Install email app on a stable container with patches. Ensure that all files in
/etc/dovecot/conf.d/ are linked properly to 2.3 versions. TLS configuration is
accurate. Use Sogo to test login and sending mails.

- Install email app on a stable container without patches. Apply patches. Ensure
that all files in /etc/dovecot/conf.d/ are linked properly to 2.3 versions. TLS
configuration is accurate for dovecot 2.3. Use Sogo to test login and sending
mails. Perform distribution upgrade to testing. Ensure that all files in
/etc/dovecot/conf.d/ are linked properly to 2.3 versions. TLS configuration is
accurate for dovecot 2.4. Use Sogo to test login and sending mails.
